In the circuit shown in Fig. P30.61, E = 60.0 V, R1 = 40.0
Chapter 30, Problem 30.61(choose chapter or problem)
In the circuit shown in Fig. P30.61, E = 60.0 V, R1 = 40.0 , R2 = 25.0 , and L = 0.300 H. Switch S is closed at t = 0. Just after the switch is closed, (a) what is the potential difference vab across the resistor R1; (b) which point, a or b, is at a higher potential; (c) what is the potential difference vcd across the inductor L; (d) which point, c or d, is at a higher potential? The switch is left closed a long time and then opened. Just after the switch is opened, (e) what is the potential difference vab across the resistor R1; (f) which point, a or b, is at a higher potential; (g) what is the potential difference vcd across the inductor L; (h) which point, c or d, is at a higher potential?
